The garden, designed by landscape designers Studio Xmpl, was launched yesterday as part of the first National Clean Air Day held in the UK. It will remain in place for two years as part of a Low Emission Neighbourhood (LEN) project around the Barbican, Guildhall and Barts hospital area.
The City of London LEN is one of five that will be set up across eight boroughs that will come into full effect by the start of 2019.
The garden also forms part of the City in Bloom Air Quality Challenge ‘Clean and green in seventeen’ which is linked to the Royal Horticultural Society’s Greening Grey Britain campaign. It was created by Friends of City Gardens and CoL volunteers and will be maintained by the City Gardens team.
Chairman of the CoL’s Environment Committee Jeremy Simons said: "The completion of this pop-up garden is a sign of things to come with the development of the LEN.
"Working in partnership with the Friends of City Gardens has once again demonstrated the demand by the local community for solutions to tackle the air quality in the Barbican and Golden lane areas.
"I hope this garden inspires visitors to think about what they can do to support the LEN and help improve air quality throughout the City."
Friends of City Gardens representative Sarah Hudson added: "We are very conscious about air quality in this area and I’m glad that this is one of the methods we are using to improve the environment.
"Over 500 volunteer hours have been contributed by residents and City workers to create this garden. A lot of thought has gone into using plants that are effective in areas of high pollution.
"I hope that this great community project will be enjoyed by everyone and I encourage visitors to come down and see how we’ve been able to tackle this problem directly"
CoL has had a City Air Programme for several years. It protects and conserves 18 major green spaces in London and south east England – including two ancient woodlands - and over 200 smaller ones in the Square Mile.
